City of Ramsey 15153 NOW"THEN BOULEVARD N.¢,., RAMSEY, MtNNESOTA55303 ~, (612) 427-1410 October 31, 1991 Mr. R/chard Sybrant 9421 West River Road Minneapolis, MN 55,!.44 Dear Mr. Sybrant: I have reviewed your request for the vacation of a portion of a cLm/nage easement located on Lot 2, Block 2, The North Forty 3rd Addition within the City. of Ramsey. It is my understanding the size of this drainage easement was first calculated based upon a drainage plan which had anticipated this easement receiving a substantial amount of drainage from 155th Lane N.W. Apparently, at the time of paving, the s~reet grades were such that mn-off from 155th Lane and a portion of Hedgehog Street were diverted entirely to the drainage easement located south of the subject lot into another drainage easement located in Block One. This modification reduced the amount of contributing impervious pavement area by more than 50%. Nonetheless, a substantial area of approximately 24 acres in both the subdivision and unplatted lands immediately to the northeast will drain to this low point. Under normal summer rainfall conditions, there will not be a problem with flooding. However, under certain melt and rainfall conditions which might occur in the early spring when ground is frozen, the need for this particular easement x~411 be substantial. It is noted that the shape of the easement does not conform vAth the naturalh, occurr/ng low area. It should also be noted that the proposed ~ading of the drainage easement ponding area has not been completed for this particular easement. Based upon the above, it is my recommendation that a vacation of the drainage easement as proposed be ~._m'anted contingent upon the develor~er submin:ing and consrructin~ a revis~ pondmg depression having a capaci~' equal to that originally approved and furnishing the City with an easement over said revised pondmg area. If you have any questions prior to the meeting on November 5.1,o91. please call. Sincerely, SJJ:c~
